Network Media Converter EFB Elektronik EL023V2

The EFB Elektronik EL023V2 is a compact network media converter that converts 100Base-TX (RJ-45) to 100Base-FX (SC) fiber. It supports Fast Ethernet data rates (10/100 Mbit/s) with a maximum transfer distance up to 2000 m over multimode fiber at 850 nm. The unit comes in a metal housing and includes an external power supply; it can be used as a single standalone device or mounted in a compatible chassis (EL0CH1).

Advantages

The converter provides autonegotiation and Auto MDI/MDI-X for simplified Ethernet connection setup and includes diagnostic LEDs for quick status checks. Its metal enclosure ensures mechanical durability while the SC multimode fiber interface offers reliable optical connectivity. The compact size and included external power adapter make it suitable for deployments where space and straightforward installation are important.

Suitable for

• Extending 10/100 Mbit/s Ethernet links over multimode fiber
• Connecting copper Ethernet devices to fiber infrastructure
• Use in small network racks or as a standalone media converter

How to use

Place the EL023V2 on a flat surface or mount it in the compatible EL0CH1 chassis if rack installation is required. Connect the copper Ethernet device to the RJ-45 port and attach the multimode SC fiber to the fiber port. Plug in the supplied external power adapter and verify power and link status via the diagnostic LEDs. The converter supports autonegotiation and Auto MDI/MDI-X, so no manual crossover or speed configuration is needed in typical setups.

Recommendations

For reliable optical performance, use multimode fiber rated for 850 nm and keep connectors clean. When installing over long distances, verify fiber continuity and attenuation to ensure the link stays within the specified 2000 m range.
